Contagious switching (or a positive network effect) can be driven by information-based social learning, as well as other mechanisms related to network size. Although previous marketing literature has documented the social-learning effect, most of the applications studied involve products in which consumers usually do not enjoy any direct benefits from a large network other than from information-based social learning. We explore the importance of the social-learning effect relative to other mechanisms that may also lead to the network effect. We propose a dynamic structural model with interpersonal interactions. To model the social-learning effect, a consumer uses feedback from his or her contacts who have switched from a focal carrier to update his or her quality expectations of alternative carriers. Our model further accounts for two unique aspects of consumer strategic learning: (i) the individual’s perception on the signal of alternative carriers from contacts who switch is systematically different according to whether the signal comes from a loyal contact; and (ii) that the perceived noisiness of the signal on alternative carriers from a contact who has switched depends on the strength of the relationship between the individual and the contact. The remaining network effect not captured through social learning is modeled as a function of the size of the network. We solve the model with a two-step dynamic programming algorithm, with the assumption that a consumer is forward-looking and decides whether to stay with the same service carrier in each period by maximizing the total utility received from that day onward. We apply the proposed model to the data set of a mobile network operator in a European country. We find that churning/switching behavior is contagious in the network context and that one-third of general network effects can be attributed to social learning. We also detect strategic learning by consumers from their contacts in two ways: the experience signal on alternative carriers from a more loyal contact who has switched from the focal carrier is perceived to be more positive than that from a less loyal contact; and the social-learning effect is stronger from an individual’s closest contacts. The simulation analysis demonstrates the value of our model in helping a company prioritize its customer relationship management effort.}, Doi = {10.1287/mnsc.2018.3173}, Key = {fds346772} } @article{fds338620, Author = {Cabral, L and Wang, Z and Xu, DY}, Title = {Competitors, complementors, parents and places: Explaining regional agglomeration in the U.S. auto industry}, Pages = {1-29}, Publisher = {Elsevier BV}, Year = {2018}, Month = {October}, url = {http://dx.doi.org/10.1016/j.red.2018.01.006}, Abstract = {© 2018 Elsevier Inc. Taking the early U.S. automobile industry as an example, we evaluate four competing hypotheses on regional industry agglomeration: intra-industry local externalities, inter-industry local externalities, employee spinouts, and location fixed effects. Our findings suggest that in the automobile case, inter-industry local externalities (particularly from the carriage and wagon industry) and employee spinouts (particularly due to the high spinout rate in Detroit) play important roles. The presence of other firms in the same industry has a negligible or negative effect. Finally, local inputs account for some agglomeration in the short run, but the effects are much more profound in the long run.}, Doi = {10.1016/j.red.2018.01.006}, Key = {fds338620} } @article{fds339234, Author = {Roberts, MJ and Xu, DY and Fan, X and Zhang, S}, Title = {The role of firm factors in demand, cost, and export market selection for chinese footwear producers}, Journal = {Review of Economic Studies}, Volume = {85}, Number = {4}, Pages = {2429-2461}, Publisher = {Oxford University Press (OUP)}, Year = {2018}, Month = {October}, url = {http://dx.doi.org/10.1093/restud/rdx066}, Abstract = {© The Author(s) 2017. Published by Oxford University Press on behalf of The Review of Economic Studies Limited. In this article, we use micro data on both trade and production for a sample of large Chinese manufacturing firms in the footwear industry from 2002 to 2006 to estimate an empirical model of export demand, pricing, and market participation by destination market. We use the model to construct indexes of firm-level demand, marginal cost, and fixed cost. The empirical results indicate substantial firm heterogeneity in all three dimension with demand being the most dispersed. The firm-specific demand and marginal cost components account for over 30% of market share variation, 40% of sales variation, and over 50% of price variation among exporters. The fixed cost index is the primary factor explaining differences in the pattern of destination markets across firms. The estimates are used to analyse the supply reallocation following the removal of the quota on Chinese footwear exports to the EU. This led to a rapid restructuring of export supply sources on both the intensive and extensive margins in favour of firms with high demand and low fixed costs indexes, with marginal cost differences not being important.}, Doi = {10.1093/restud/rdx066}, Key = {fds339234} } @article{fds343255, Author = {Chen, Z and Liu, Z and Suárez Serrato and JC and Yi Xu, D}, Title = {Notching R&D Investment with Corporate Income Tax Cuts in China}, Year = {2018}, Month = {June}, Key = {fds343255} } @article{fds331945, Author = {Fieler, AC and Eslava, M and Xu, DY}, Title = {Trade, quality upgrading, and input linkages: Theory and evidence from Colombia}, Journal = {American Economic Review}, Volume = {108}, Number = {1}, Pages = {109-146}, Publisher = {American Economic Association}, Year = {2018}, Month = {January}, url = {http://dx.doi.org/10.1257/aer.20150796}, Abstract = {A quantitative model brings together theories linking international trade to quality, technology, and demand for skills.

We study a model of establishment dynamics in which financial frictions reduce TFP through two channels. First, finance frictions distort entry and technology adoption decisions. Second, finance frictions generate dispersion in the returns to capital across existing producers and thus productivity losses from misallocation. Parameterizations of our model consistent with the data imply fairly small losses from misallocation, but potentially sizable losses from inefficiently low levels of entry and technology adoption.

Entry costs faced by potential entrants, fixed costs faced by incumbent producers, and the toughness of short-run price competition are important determinants of long-run firm values, firm turnover, and market structure. In the dentist industry entry costs were subsidized in geographic markets designated as Health Professional Shortage Areas (HPSA) and the estimated mean entry cost is 11 percent lower in these markets. Using simulations, we find that entry cost subsidies are less expensive per additional firm than fixed cost subsidies. © 2013, RAND.}, Doi = {10.1111/1756-2171.12027}, Key = {fds239256} } @article{fds328794, Author = {Roberts, M and Xu, DY and Fan, X and Zhang, S}, Title = {The Role of Firm Factors in Demand, Cost, and Export Market Selection for Chinese Footwear Producers}, Publisher = {National Bureau of Economic Research}, Year = {2012}, Month = {January}, url = {http://dx.doi.org/10.3386/w17725}, Doi = {10.3386/w17725}, Key = {fds328794} } @article{fds239260, Author = {Lederman, D and Rodríguez-Clare, A and Xu, DY}, Title = {Entrepreneurship and the extensive margin in export growth: A microeconomic accounting of Costa Rica's export growth during 1997-2007}, Journal = {The World Bank Economic Review}, Volume = {25}, Number = {3}, Pages = {543-561}, Publisher = {Oxford University Press (OUP)}, Year = {2011}, Month = {December}, ISSN = {0258-6770}, url = {http://dx.doi.org/10.1093/wber/lhr031}, Abstract = {Successful exporting countries are often seen as successful economies. This paper studies the role of new exporting entrepreneurs-defined as firms that became exporters-in determining export growth in a fast growing and export oriented middleincome country i.e., Costa Rica during 1997-2007. It provides a detailed description of the contribution of export entrepreneurs in the short and long run, and comparing the observed patterns with an emerging literature on the role of the "extensive" margin in international trade. On a year-by-year basis, the rate of firm turnover into and out of exporting is high, but exit rates decline rapidly with age (i.e., the number of years the firm has been exporting). On average, about 30 percent of firms in each year tend to exit export activities, and a similar percentage of firms enter. The exiting and entering firms tend to be significantly smaller than incumbent firms in terms of export value (e.g., entrants export about 30 percent less on average than incumbent firms). These findings are consistent with existing evidence for other middle income Latin American countries. However, in the long run new product-firm combinations (i.e., product-firm combinations not present in 1997) account for almost 60 percent of the value of exports in 2007. Surviving new exporters actively adopted new products (for the firm, but not necessarily new for the country) and abandoned weaker existing products they start with, and their export growth rates were very high during a period (1999-2005) when those of incumbent exporting firms were actually negative. © The Author 2011.

What is the impact of these policies on productivity measures, the equilibrium number of establishments and their size distribution? We find that these effects are potentially large: policies that reduce the average size of establishments by 20% lead to reductions in output and output per establishment up to 8.1% and 25.6% respectively, as well as large increases in the number of establishments (23.5%). © 2008 Elsevier Inc.

In the model, production requires a managerial input, and individuals sort themselves into managers and workers. Since managers are heterogeneous in terms of their ability, establishments of different sizes coexist in equilibrium in each sector.
